Hi. As the article says Changing behavior of “gl” and “glcore” video drivers From which version are these changes? It does not say in the article and not on twitter.
Where are these options? “Allow cores to change video drivers” “Shared hardware context”
Nightlies or the upcoming stable (whenever it’s released).
Settings > core. This is an “advanced” settings menu, so you won’t see it unless you go to settings > user interface > show advanced settings ON.
aaaaaaah… no wonder I did not see them, I spent about 3 days looking for them line by line. 
Thank you!
